At the Global Population?

A popular estimate for the sustainable population of earth is 8 billion people as of 2012. With the world population at 7.8 billion people as of March 2020 and typical projections of population growth, Earth will be in a state of human overpopulation by 2050 or sooner.

What was the global population in 2019?

The world's population continues to grow, albeit at a slower pace than at any time since 1950 (figure 1). The world's population reached 7.7 billion in mid- 2019, having added one billion people since 2007 and two billion since 1994.

How accurate is the world population?

Researcher Nico Keilman did that, and found that the UN has an impressively accurate track record at population predictions. Their estimates of world population by 1990, published in 1950, were off by about 12 percent. So up to the present day, the UN has been highly reliable in predicting global population trends.
